As voters in Iowa prepare to decide on whether to retain three state Supreme Court justices who ruled last year to legalize gay marriage, one pastor is calling on Christian leaders to shine a spotlight on "out of control" judges.

"Our freedoms are in peril today because of judges - not legislators - but judges," Jeff Mullen, senior pastor of Point of Grace Church in Waukee, told The Iowa Independent.

"Inform your congregation about the importance of the judicial retention election and what it means to turn the ballot over and vote their values," he added.

Mullen spoke more about out of control judges on CBN News Channel Morning News, Oct. 27. Click play to watch.

Mullen has created a website, IowaPastors.com. The goal of the website is to "build strategic partnerships to mobilize pastors and congregations to pray effectively and to vote righteously."

However, concerns abound that Mullen's call to action may be prompting churches to violate a federal tax law that forbids 501(c)3 organizations from intervening in elections in support of or opposition to any candidate.

"The problem occurs when religious leaders tell people which candidates to support or not support," explained Rob Boston, senior policy analyst with Americans United.

"They can even speak about issues," he said. "They can speak out against abortion. They can speak out against same-sex marriage. They simply cannot take the next step of advising congregants on how to vote."
